SLICING MACHINE.

This invention relates to machines for slicing meat, bread or other. commodities, and has for its object the provision of a machine of the class named which shall be of improved construction and operation and which shall have improved mechanism for holding the material and presenting it to the slicing knife, so that an entire piece may be sliced without re-clamping.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims. a

In the drawings Fig. 1 is a side elevation of a slicing machine, having one embodiment of the present invention applied thereto.

Fig. 2 is a top plane view of the machine shown in 1. 7

As illustrated in 10 designates the base or supporting frame of the slicing machine having ways 11 upon which a table 12 is mounted to reciprocate.

A. link 13 is connected at 14 to the underside of the table 12 and is pivoted at its opposite end to a crank arm 15 carried by an upright stud shaft 16 'journalled in the frame 10.

A bevel gear 17 is secured to the lower end of the stud shaft 16 and meshes with a pinion 18 secured to a drive shaft 19. A hand-wheel 20 is mounted on the drive shaft 19, to operate the. slicing machine. I A second pinion 21 meshes with the gear 17 and drives the rotating knife 22 by means of a shaft 23 and a sprocket drive arranged within a chain box and knife support 2 1.

The table 21 is provided with an upright abutment plate 25 at the side adjacent the hand wheel 20. A feed plate 26 is slidably mounted on the table 21 and guided by grooves 27 at the opposite sides of the table.

,- The plate 25 carries upright posts 28, on

which there is adjustably mounted a top grip 29. A plate 30 is supported between the posts 28 and is provided with a side grip 31 adjustable in slot 32 in the plate 30 and held in place by a wing nut 33. g

The upper face of the table 12 is provided with corrugations 34 extending parallel with the abutment 25. The material to be sliced is placed directly upon the upper face of the table 12 with one side against the steam abutment 25 and the rear end against the from the abutment plate 2.5and thecutting plane of the knife, and the top grip 29 is forced downwardly to engage the top face of the piece adjacent the rear end. The plate 26 is fed forwardly step by step by means of a feed screw 35 and ratchet mechanism 86 of well known construction. V

The force exerted by the knife 22 during a cutting operation is counteracted by the abutment plate 25 and the upper surface of the table 12. The side clamp 31 and the top clamp 29 assist in overcoming anyforward pull on the piece and in resisting any turning moment exerted by the knife.

With this mechanism it is possible to clamp a piece of meat or loaf of bread'adjacent one end and to slicethe entire piece p g p without removing or re-clamping the piece. the drawings, numeral.

In order to prevent the operator from inserting his hand between the knife and the abutment 25, aguard plate 37 is supported adjacent the path of movement of the table .12 in position to completely close the space between the knife and abutment 25 when the .table is in position to begin a slicing movement.

The operating handle 38 for the top grip 29 is preferably arranged at theside of the table 12 away from the abutment 25, s0 that the abutment will not interfere with the operation of the top grip. The grip may be positioned by reaching across the table when the table is in the position shown in Fig. 2. or the operatormay stand at the rear of the slicing machine while clamping the piece in place. Since the piece requires but a single clamping operation for a complete slicing, there is little inconvenience incident to setting the top clamp.

I claim: i p i a 1. A slicing machine comprising aknife,a

table arranged to reciprocate relative to said knife, an abutment on said table extending table, a knife disposed adjacent the path of movement of said table, an abutment plate extending along said table substantially perpendicular to the cutting plane of said knife, a follower for engaging the rear port-ion of material on said table, means for feeding said follower toward the cutting plane of said knife and a guard disposed in registration with the opening between said knife and abutment when said table is at the be ginning of a slicing movement. and extending substantially into registration with the cutting edge of said knife.

3. A slicingmachine comprising a reciprocating table, a knife having its cutting plane disposed adjacent the path of movement of said table, an abutment extending along one side of said table substantiall perpen dicular to the cutting plane of said knife, a follower having a side grip thereon for engaging the rear portion of a piece to be sliced at the side away from said abutment, means for feeding said follower toward the cutting plane of said knife and a guard plate arranged at one side of said knife and adjacent to and parallel with the cutting plane thereof and extending substantially into registration with the cutting edge of said knife.

4-. In combination a slicing knife. a table arranged to reciprocate adjacent the cutting plane of said knife and movable to a position at one side of said knife to begin a cutting stroke an abutment arranged at the side of said table away from said knife at the beginning of a cutting stroke and substantially perpendicular to the cutting plane of said knife, and a guard extending substantially parallel with the cutting plane of said knife and extending substantially into registration with the cutting edge of said knife to protectthe space between said knife and abutment at the beginning of a cutting stroke.

5. In combination a slicing knife, a table arranged to reciprocate adjacent the cutting plane of said knife and movable into position at one side of said knife to begin a slicing stroke, and a guard plate arranged in registration with the opening between said knife and abutmentwhen said table is in position to begin a slicing stroke and extending substantially into registration with the cutting edge of said knife.

6. In combination aslicing knife, a table arranged to reciprocate adjacent the cutting plane of said knife and movable to one side of said knife to begin a cutting stroke. an abutment at the side of said table away from said knife when said table is in position to begin a cutting stroke, a follower for feeding material along said abutment toward the cutting plane of said knife. and a guard plate substantiall closing the opening between said knife and abutment when said table is in position to begin a cutting stroke, said guard plate being positioned adjacent the cutting plane of said knife but spaced therefrom at the side thereof awa from said table.

7. It slicing machine comprising a knife, a table arranged to reciprocate adjacent the cutting plane of said knife, an operating crank disposed at one end of the path of movement of said table, an abutment on said table at the side thereof adjacent said operating crank, and a fixed guard plate arranged at the side of said knife toward said operating crank and spaced from the path of movement of said table at the side of the cutting plane of said knife away from Hlltl table and extending substantially into registration with the cuttin edge of said knife.

8. A slicing machine comprising a supporting frame, a table arranged to reciprocate on said frame, a slicing knife disposed adjacent the path of movement of said table, an operating crank mounted on said frame at one end of the path of movement of said table, said table being movable past .-aid knife at the side thereof adjacent said operating crank, an abutment at the side of said table adjacent said operating crank, a follower for engaging the rear end of the piece of material on said table, means for feeding said follower in a direction parallel with said abutment to move the material on said table toward the cutting plane of said knife, and a guard plat arranged at the side of the cutting plane of said knife away from said table and registering with-the opening between said knife and abutment when said table is at the end of its stroke adjacent said operating crank and extending sul'istantially into registratirm with the cutting edge of said knife.

in testimony whereof I have signed my name to this specitication on this 22nd day of June A. D. 1925.
